Energy absorption of bio-inspired multi-layered graded foam-filled structures under axial crushing

, 2020
In this paper, an innovative bio-inspired multi-layered graded foam-filled structure (MGFS) mimicking the characteristics of the human skeleton was proposed in an attempt to improve the energy absorption. The proposed structures consisted of three layers

Energy Absorption Devices

1972
An ironic consequence of modern highways has been the emergence of new types of accidents. Recent investigations (1) have shown that "running off the road" may be the largest, single cause of fatalities on limited access, multilane roads. According to the 1967 Report of the Special AASHO Traffic Safety Committee ("Yellow Book") (2) the rate of ...

Solar energy absorption by acrylic coatings–I: absorption characteristics

Building and Environment, 2004
This paper presents the results of a larger study on application of acrylic plasters as external coatings in the passive heating systems. The efficiency of the heating system strongly depends on the physical and optical properties of the used materials, especially those used for the finishing coatings. Absorption characteristics as a function of colour

Mechanical design and energy absorption performances of novel dual scale hybrid plate-lattice mechanical metamaterials

, 2020
In this paper, novel dual scale hybrid mechanical metamaterials consisting of simple cubic structure (SC), body-centered cubic structure (BCC), face-centered cubic structure (FCC) unit cells at different scale levels were designed and proposed for impact

Ultra-low density architectured metamaterial with superior mechanical properties and energy absorption capability

, 2020
The material with negative Poisson's ratio (NPR) is a typical metamaterial, which is considered to have great prospects in energy absorption, but the low modulus and low strength of the materials are the biggest obstacles to its engineering applications.
